scope:

This Recommendation specifies requirements for the design of inclusive audio-based network navigation systems (IABNNSs) to accommodate users with vision impairment as well as users with a wide range of characteristics and capabilities. This Recommendation aims to help design professionals to achieve an inclusive environment through IABNNSs that augment the physical environment by the provision of aural information about environments for users. This Recommendation does not consider the specialized requirements of people who are deaf or hard of hearing.

In addition, while this Recommendation recognizes the necessity of providing audio-based network navigation outputs in languages determined by the user, it is beyond scope of this Recommendation to provide a specific solution. However, implementers should not implement an audio-based network navigation solution that only uses the English language. Future work aims, among other things, to address this issue, and will explore the use of meta-coding for providing a flexible usercentric translation system.
